Infant ABR: Tone Burst vs CE-Chirp Octave Band

---

1.  Air-conducted CE-Chirp Octave Band stimuli have spectra that is: Narrower than tone burst stimuli Wider than tone burst stimuli Identical with tone burst stimuli None of the above

2.  ABR Wave V Latencies for air-conducted CE-Chirp Octave band Stimuli are: Earlier for 500, 1000 and 2000 Hz than traditional tone bursts at the same frequencies Later for 500, 1000 and 2000 Hz than traditional tone bursts at the same frequencies The same for 4000 Hz CE-Chirp Octave Band and 4000 Hz Tone Burst A & C

3.  ABR Wave V amplitudes to air-conduction CE-Chirp Octave band stimuli are Significantly larger than tone burst stimuli at 500 Hz at 60, 45 and 30 dB nHL Significantly smaller than tone burst stimuli at 1000 and 2000 Hz at 60, 45 and 30 dB nHL and 4000 Hz at 45 and 30 dB nHL Significantly larger than tone burst stimuli at 1000 and 2000 Hz at 60, 45 and 30 dB nHL and 4000 Hz at 45 and 30 dB nHL Identical at all frequencies and intensities

4.  ABR Wave V latencies for air-conducted tone bursts: Increase with increasing frequencies Decrease with increasing frequencies Stay the same at all frequencies None of these

5.  ABRs Wave V amplitudes for air-conducted CE-Chirp Octave Band stimuli in infants versus adults are: Significantly smaller in adults than infants Significantly larger in adults than infants. About the same at all frequencies except 500 Hz. None of the above

6.  ABRs Wave V latencies for air-conducted CE-Chirp Octave Band stimuli in infants versus adults are: Significantly later in infants than adults. Significantly earlier in infants than adults. About the same at all frequencies except 500 Hz. None of the above

7.  The timing for the CE-Chirp Octave Bands: Starts at 0 ms. Is derived from the CE-Chirp Precedes O ms. Both B & C

8.  The earlier wave V latencies for adults than infants are believed to result from: Maturation of the central auditory system Middle ear issues and / or vernix in external canal of infants Faster conduction time of infant neural pathway A & B

9.  In relation to the timebase for Tone Bursts, the recording window for CE-Chirp Octave Bands can Be increased beyond Tone Burst Window Be decreased from Tone Burst Window Stay the same. None of the above

10.  The filter setting for recording CE-Chirp Octave Bands is 100-3000 150 - 2000 30 - 3000 30 - 1500
